There is no one "best" way to install wainscoting. Some people prefer to use a miter saw to cut the top and bottom railings to length, while others may find it easier to simply cut them to size with a hand saw. Once the railing pieces are cut to size, you will need to decide how you want to attach them to the wall. Some people choose to use construction adhesive and nails or screws, while others may choose to use wood glue and staples. It's important that you make sure the wainscoting is level before attaching it permanently to the wall. You can do this by using a level or by measuring from corner-to-corner.

There is no one-size-fits-all answer to this question, as the best way to install wainscoting will vary depending on the specific situation. However, some tips on how to install wainscoting include measuring accurately and cutting the panels to size before installation, using a level when installing, and making sure that the screws are tight against the wall.
